Yes they did and it came back to bite them on the rear-end. Russell believed the Church, the body of Christ was a numbered class, 144,000. He believed that the Great Company was made up of those who were called, but didn't make their "calling and election sure", because "many are called and few are chosen." That didn't mean that those who weren't chosen failed miserably and were deserving of second death, only that they just didn't measure up to God's ultimate standard, and so instead of sitting ON thrones, wearing crowns, they stand BEFORE the throne with palm branches. The rest of mankind will inherit the earth.
Somehow, Rutherford decided that his followers were growing; they were numbering more than 144,000. How can that be? Instead of leaving it in the Lord's hands as to the many called and few chosen. He decides to introduce new light. Claims the great company is an earthly class, because the door to heaven was shut in 1935. So this group of earth dwellers was created based on a date, 1935, and from that moment on, they began to gather from among humanity those who will inherit the earth and be a part of this great company. The rest of mankind will perish at Armageddon. As you well know, they have refined this teaching through the years. They ran out of redefining the "generation of 1914" and not too long ago, the Governing Body did away with the 1935 date. This of course causes a problem, if 1935 is no longer a scriptural teaching, a teaching that created the great company gathered as of 1935, thus closing the door to the high calling in that year, then how can they continue to teach the existence of this group, based on a false and discarded belief system? If you toss out 1935, then you have to toss out what supposedly occurred in that year. And if you keep the belief that the great company is an earthly class, when did it start?
